22 years old Technics with Origin Live OL1 arm and DL-103R, aligned, tested and measured. Everything is within +/- 1.2 db (Very flat in the audible range just curving up at the extremes), with a little bump at +2 db around 15khz. Seems to be intentional from Denon, judging by the near-identical measurements supplied by with two DL103Rs bought 10 years appart.
